CORN PLANTER.

SPECIFICATION forming part of Letters Patent No. 264,419, datedSeptember 12, 1882.

Application filed May 5, 1882. (ModeL) To all whom it may concern:

Be it knownthat I, JOSEPH D. SMITH, of Rockford, in the county ofWinnebago and State of Illinois, have invented certain newand usefulImprovements in Corn-Planters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification, and in whichFigure 1 is a plan view. Fig. 2 is aside elevation with the wheelsremoved. Fig. 3 is a vertical section of one of the wheels. Fig. 4is alongitudinal section through the hopper. Fig. 5 is a perspective view ofthe seed-slide and the bottom plate of the hopper. Fig. 6is a sectionthrough the cut-off.

The nature of my invention consists essentially in a rectilinearreciprocating slide having two rotary perforated disks arranged todischarge the grain through the same orifice; also, in such otherarrangement of parts as will be hereinafter described and claimed.

A designates a draft-frame, of which B is the tongue, and O G thesupporting-wheels, which are applied on inclined axle-arms directeddownward,outward,and forward. These wheels 0 O are made of metal, andthey are beveled, so that they cut into the soil and press it to oneside, so as to form drills or furrows adapted to receive the corn. -Onthe inner sides of the drill-opening wheels 0 O are shoes or drags D D,which are made of springy metal and secured at their front ends to thefront transverse bar of the frame A. From these points the shoes extenddownward and backward, and their rear 'extremities,a a, are twisted soas'to be directed inwardly, as shown in Fig. 1. The rear portions of theshoes D I) have secured to them rods E E, which have screw-threads cuton their upper ends. These rods pass freely through brackets G, whichare secured to the rear bar of the main frame, and above said bracketsare adjusting-nuts b, for setting the shoes, and below the brackets arejam-nu'ts'c, for fixing theshoes at the desired point.

Between the-wheels O O and the shoes D D are tubes H H, which aredirected downward and backward, and at the upper termini are tables I I,which are horizontal. Upon these tables are suitably-securedhopper-boxes J J. Each hopper-box is secured to the table I, and alsohas rigidly secured to it a metal frame, K, to which screw-bolts areapplied. These screwbolts pass through cars, which are offsets of theframe K, and they are adapted to receive nuts on their lower ends. Tnisframe K is also constructed with a box, L, which tapers downward, andwhich receives in it two blocks, L L. This box L is also constructedwith sockets and with holes through the sockets concentric to them. AWearing-surface is also formed on the bottom of the frame K. The blocksL have studs 0 e rigidly secured to them, which receive around themhelical springs ff, the upper ends of which are received in the socketsof the boxes J. These blocks L are grooved horizontally to receive apin, h, and their lower ends are scored out, as shown at These blocks Lare gages, which press upon a reciprocating slide, M, and also upon thesurfaces of intermittently rotating periorated distributers N. Thesedistributers are let into the slide M flush with the upper surfacethereot', and 1 hey have perforations through themsay three in number,respectivelywhich are-equidistant from the centers of the distributers.The bottoms of the distributers have circular central hubs, from whichradiate at three points fins j, (shown in the bottom view, Fig. 5.) Theparallel edges of the slide M have ribs on their lower sides, which areprovided with offsets Is. This slide M is also provided with transverseflanges Z Z l and an end transverse flange, m.

The plate 0 is constructed with lips and ears, a straightguide, and anopening through it. The lips m m are guides for the slide M, the ears nn are abutments for the wings j of the distributing-wheels, and thestraight guide 19 is designed for keeping the holes in proper registerwith respect to the opening 0 through the base-plate.

It will be seen from what I have above set forth that I have combinedwith a rectilinear slide an intermittent rotary distributor...

Itwill also be seen that I have rotary furrowformers combined withdrags, which smooth one side of the furrow.

Having described my invention, I claim- 1. In a corn-planter, therectilinear reciproeating slide M, provided with two rotary perforateddisks, N N, both constructed and arranged to discharge the grain throughthe same orifice, substantially as set forth.

2. The rectilinear reciprocating slide M and base-plate 0, bothconstructed substantially as described, in combination with two rotaryperforated disks, N N, adapted to discharge the grain through a commonorifice, all substantially as set forth.

3. The combination, in a corn-planter, of the reciprocating slide M,having ribs k 75 and transverse flanges l l l and m, with base-plate Oand two rotating disks, N N, adapted to discharge the grain through acommon orifice, all

substantially and for the purpose set forth.

my own I affix my signature in presence of 0 two witnesses.
